[PATCH] [TRIVIAL] perf probe usability related fixes.

[PATCH] [TRIVIAL] perf probe usability related fixes.

[Srikar Dronamraju]

From: Srikar Dronamraju <srikar@linux.vnet.ibm.com>

Ingo pointed out few perf probe usability related errors during
his review of uprobes.

Since these issues are independent of uprobes, fixing them in a
separate patch.
